Panadapter fails with multiple TNFs open

During the field day event; I used TNFs to mark who I talked to on the Pan adapter top section. I understand that this is not the purpose of TNF, however, this was a way to mark the Pan Adapter of who I had made contract with on the band during the contest.

When I used a lot of TNFs (probably 40 or more); the pan adapter (top section, with the TNFs) did not move when I panned the band (right click hold and drag to move the screen over); the bottom section (waterfall) moved, the top section remained in place; not synchronized anymore.

Solution; reboot. When i reboot; the same pan adapter, with the 40 or so TNFs, opened again as expected; the same thing happens; so reboot, and remove TNFs to resolve.

<< it would be NICE (please-please-pretty-please with sprinkles on top) in future software upgrades to have a "method to mark / unmark - maybe with call signs" (on the pan adapter's top section) so we can figure out which signals we talked to or not during contest.>>
